Summary

Fixes a correctness bug in .

The Kubernetes YAML example showed , but the
accompanying note states the value "should exceed the healthcheck failure threshold
(3 × 30s = 90s)". With 30s < 90s, Kubernetes sends SIGTERM and waits only 30s
before SIGKILL — potentially killing the pod before the graceful shutdown (~3s via
) completes.

Changed to (exceeds the 90s threshold by 30s) and the note is updated to
explain the buffer.

Covers Docker image pull, required env vars (MOLECULE_API_URL,
MOLECULE_API_KEY, WORKSPACE_ID, PORT), built-in HEALTHCHECK probe
(/agent/card every 30s), Docker Compose config, graceful SIGTERM
shutdown via stop_event threading.Event, and Kubernetes liveness/readiness
probe configuration.

Closes gap: no self-hosted Docker workspace deployment docs existed

fix(docs): set terminationGracePeriodSeconds to 120 in Kubernetes YAML example
Secret scan / secret-scan (pull_request) Successful in 1s
Details
CI / build (pull_request) Successful in 4m4s
Details
644226f2b2 
The example showed terminationGracePeriodSeconds: 30, but the accompanying
note says the value "should exceed the healthcheck failure threshold
(3 × 30s = 90s)". With 30s < 90s, Kubernetes would send SIGTERM and
wait only 30s before SIGKILL — potentially killing the pod before the
graceful shutdown (3s via stop_event) completes.

Changed to 120s, which exceeds the 90s threshold and aligns the YAML
example with the documented requirement.

PR #46 Review — REQUEST CHANGES

The terminationGracePeriodSeconds: 120 fix is correct. However, this PR cannot merge in its current form for two reasons:

Issue 1: Base conflict with PR #40

PR #46 is based on the original commit b6e3b8e — before the PR #40 corrections. PR #40 (approved, SHA b12527b) is ready to merge and already includes the terminationGracePeriodSeconds: 120 fix along with all other corrections. If PR #46 merges first, the same lines will conflict when PR #40 tries to merge.

Recommend: close this PR as redundant. PR #40's merge will deliver the correct Kubernetes YAML.

Issue 2: Math error in the note

The note says 3 x 30s = 90s. This is incomplete — the liveness probe also has initialDelaySeconds: 30, so Kubernetes does not begin counting failures until 30s have elapsed. The actual failure window is:

30s (initialDelay) + 3 x 30s (failureThreshold x period) = 120-150s

90s underestimates the failure threshold by 30s. The correct calculation is documented in PR #40's note: "120-150s with the current probe config".

If this PR were to be merged standalone (not rebase-closing), the note should read:

terminationGracePeriodSeconds must exceed the liveness probe failure window
(30s initialDelay + 3 x 30s period = 120-150s). The 120s value here
is the minimum safe setting; 150s is recommended for production.

Recommendation

Close PR #46 as redundant. PR #40 (commit b12527b) delivers the same fix plus the corrected note.

PR #46 Review — REQUEST CHANGES (re-review after new commit)

The CI workflow addition is separate from the documentation content and may be fine on its own — I have not reviewed it in detail.

However, the self-hosted-workspace-docker.md content in this PR is the original unfixed version (from commit b6e3b8e) and contains all the same errors from my previous review:

Still broken in this PR

  1. MOLECULE_API_URL in env vars table — the workspace runtime env var is PLATFORM_URL, not MOLECULE_API_URL. Verified against workspace/main.py:85.
  2. MOLECULE_API_KEY in env vars table — not a real workspace runtime env var. The workspace obtains its bearer token automatically from the platform during registration.
  3. AGENT_CARD_URL in env vars table — not a real env var. The workspace generates its URL internally from HOSTNAME+port.
  4. Healthcheck at /agent/card — the actual endpoint is /.well-known/agent-card.json (A2A workspace agent, verified via boot_routes.py).
  5. Python example uses RemoteAgentClient — this class does not exist. The correct class is HeartbeatLoop from workspace/heartbeat.py.
  6. terminationGracePeriodSeconds: 120 + incorrect note — the value is correct (changed from 30), but the note still claims 3 × 30s = 90s. The actual failure window is 30s initialDelay + 3 × 30s = 120–150s.

Redundant with PR #40

PR #40 (SHA b12527b, branch docs/self-hosted-workspace-docker, APPROVED) already has all these corrections. Merging this PR would conflict with PR #40.

Recommendation

Close this PR as redundant. PR #40 delivers the correct Docker tutorial content.

Re-review: self-hosted Docker tutorial (docs PR #46, commit d74e796)

File reviewed: content/docs/tutorials/self-hosted-workspace-docker.md

All four prior issues — resolved ✅

  1. terminationGracePeriodSeconds: 120 ✅ — Kubernetes YAML now has terminationGracePeriodSeconds: 120 with a correct explanation: "With periodSeconds: 30 and failureThreshold: 3, the probe does not register a failure until approximately 120–150s after the container becomes unhealthy." Set to 120 or higher. Matches the liveness probe threshold as intended.

  2. PLATFORM_URL env var ✅ — Environment variables table shows PLATFORM_URL defaulting to http://localhost:8080, with explicit note that containers must use http://host.docker.internal:8080. Docker run command uses the correct container-appropriate value.

  3. Healthcheck section ✅ — Step 4 covers CLI verification (docker inspect --format='{{.State.Health.Status}}'), curl against /.well-known/agent-card.json, Docker Compose healthcheck: block with 30s/5s/3 retries, and Kubernetes liveness + readiness probes on the same path.

  4. Graceful shutdown + SIGTERM ✅ — Step 5 explains the full signal chain: SIGTERM → uvicorn → heartbeat stop → adapter cancel → in-flight A2A grace period → exit. Python integration example shows HeartbeatLoop + heartbeat.stop() in finally. Docker 10s stop window noted.

Approve. Tutorial is accurate and production-ready.

PR #46 Review — APPROVED (re-review)

My prior REQUEST_CHANGES was stale. The current head (d74e796) is a comprehensive fix commit that supersedes the original. Verified:

  • terminationGracePeriodSeconds: 120 ✓
  • Correct math in note: 30s initialDelay + 3 × 30s = 120-150s ✓ (my old RC flagged the 90s error)
  • /.well-known/agent-card.json healthcheck path ✓
  • PLATFORM_URL defaults corrected to host.docker.internal:8080 ✓
  • No MOLECULE_API_KEY or fabricated env vars ✓
  • HeartbeatLoop from workspace/heartbeat.py ✓

PR #40 was closed without merging, so these corrections need to land via this PR. Ready to merge.
